D 1, 1ri`n g ,i its ,prog i ressintofthe mold', the core compresses that much of vthe,uvinaterial which can Afind a. place between the lower half of said eore andthe moldfbottom and forces the surplusmaterial around the upper half of said eoreinto4 the space between said upper halfandfthefupper mold Wall, at the same time forcingasmuch material mtothe toe or equivalentIportion itself there. ,-YilienhtheI coreA hasreached' its final innermost position in thefmold,

ofthe moldopening as can accommodate eyery part of Ithe mold has beenl filled with -Composition under lthe desired pressure,and yany surplus material which cannot vbe further compressed has been forcedsoutl of the ,openy en d 41|iofA the mold opening. It

V,.irvill v:be'understood that 'the' coreb-exing heath core or :otherwise retardfthecore in dmovement Linto the mold. v repressed. estaremos@ (F1a 5) is then allowed yto bake under the heat of the `core until suflicientl-ycaked to allow the ,Y removal of the core Without injury to the finished -Work 43, `Whereafter the core is wivithdraivn by the screwv 25 or the lever 28 as the case may be. It Will be seen that by reason of` the core being heated, said core may readily be Withdrawn from the finished article IWithout danger of injuring said laitiele. `The bednldis then lowered, the finished article 43 removed from the mold,l and the operation repeated. y

,We prefer to make the core31 conicalvin shape for the reasons .that not only isrthe material 45 better compressed and distributed I by a core ofthat shape, but that such yshape allows the easy Withdrawal 'ofl the core. from the finishedarticle, though it Will be understood that for doll parts of different shape,

the shape ofthe coremay be varied to some extent Without detracting from the eflieiency ofour device. The preferably rounded end 44ofthe coreaids in properly distributing ,the material in the mold and in preventing sticking of:y said vmaterial to lsaid core, though ,ive do not ivishto be understood as limiting I ourselves to ra corefend of that shape.

i fln' the application of our `invention ,to the manufaoture of dolls.l arms and legs, a `hol- Y low armor leg is producedat a considerable Esaving of material and-of Weight.' The size of the core is 'preferably suchfas Vwill form a Vdell part ofthe desired minimum thickness .thronghout, .though certain "portions of the party may, be' somewhat thicker than others. lt wifll be lnoted .that avcomparatively thin layer of `material is compressed i between the sore andthe mold [Walls and that less pressure on the material is', therefore, required to produce a homogeneous part than `Would ,be the ease Were'gthe partl made solid or-tvithlout the use of a core. it Willfurtherbe `,noted y,that therelbeing Vless/material to Abe baked br heated, the" ba ling" time maybe materially Vreduced 'over that requiredv in fmalring-a solid part,=and theuse of f our iiriproved` method, the entire V,parte may be made Vina single piece instead of making each half separately and then gluing "the i halves together.

Altfwllmbe' understood that heat ymay also be applied to the `molds in a manner Well A,knmvninthe art, if desired, that our vdevice Vmay, beoperatively connected to any suitable press ladapted to* make ldoll parts instead of the particularrmachine illustrated, that the vmolds and the'core may be'made to operate I `in l proper V synchronization automatically instead of manually, as illustrated', that saidv vcore and .mold may be moved relatively by l rmeans other than that illustrated, that any heating yn'lieans may be employed in place of that illustrated, thatparts other thanthe legsillustrated-maybe madeby'the use of our improvedfmethod mechanism, and

that various other changes may be madewithout departing from Vthe spirit or scope of our invention.

Ve claim: v l. The method of making hollow l doll parts closed at one endof composition, com-- prising partly'illing an open mold member with said composition, closing the mold to form a mold cavity open at one end, moving a core passed through the open end of said mold in a direction effective tov spread and compress said composition into Vall parts of said'mold, heating said core continuously, allowing the heated core to remain lin the 1 Vmold until the composition has set, and removingl the product from the mold.

2. The method of makingV hollowy doll parts closed at one `end` of composition consisting of llingan open split `mold with said composition under comparatively little pressure, closing the mold to form amold cavity open Vat one end, forcing said composition away from the central portion of saidmold and into the remainder of said mold, simultaneously heating and compressing said composition', opening said .split mold after said composition has set, ,and`

removing the product from the mold.

8. In a mechanism for making doll parts, a split mold, a hollow conical'core closed at `one end, means for continuously Vheating said core, and means formoving said core and said mold relatively for compressing the material in said moldragainst the walls of said mold, and forseparating said core and said mold.

V6. In combination with a mold for mak#v ing hollow doll part-s. closed at one end, a heated conical core closed at one end `for forming a conical recess closed at one end in said doll parts, and means for axially mov# ving said core relatively to said mold for causing said coie to partiallyl enter .said mold.

7. The combination with a split mold for making hollow composition doll parts Vclosed at one end, of an internally recessed conical coreclosecl at one end and open at the other VYmeans for reciprocating saidycore Hsaid core through the open endv thereof,V

9. The combination with amold for making hollow doll parts of a core of substan- .tially less diameter than that of the openingV Vin said mold,m eans for continuously heating said core,`and means for axially reciprocating said core into and'out of said mold. y

10. The combination with a mold fon making hollow doll parts closed at one end of a hollow conical rcore of substantially yless diameter. than thatr of theopening in said mold and open at one end thereof, a
